MANIFOLD ASSY OEM Ref. 114174 – Evergrow Part #171261 for NOV TDS-11SA Top Drive

The MANIFOLD ASSY OEM Ref. 114174, supplied by Linhai Evergrow as Evergrow Part #171261, is an important replacement component for the NOV TDS-11SA top drive hydraulic control system. Its primary function is to convert electrical control signals into hydraulic energy; by precisely regulating the direction, pressure, and flow rate of hydraulic fluid, it enables the remote and automated operation of the top drive to execute various complex mechanical actions. As part of the top drive's fluid and control circuit, the manifold assembly provides an organized connection point for associated tubing, fittings, valves, and other system components.

For drilling contractors, top drive maintenance companies, and oilfield equipment distributors, maintaining a reliable supply of critical TDS-11SA spare parts can help shorten repair time and reduce the risk of extended equipment downtime.

Evergrow's published TDS-11SA/9SA spare parts list identifies MANIFOLD, OEM Ref. 114174 / Evergrow Part #171261 as a replacement component for the TDS-11SA top drive.

Product Details of Manifold Assy 114174

A manifold is designed to bring multiple fluid or control connections together in a controlled arrangement. In a complex top drive system such as the NOV TDS-11SA, manifolds work with tubing assemblies and other hydraulic or pneumatic components to distribute or route working fluids to the appropriate circuits.

The 114174 manifold assembly is listed separately from several other TDS-11SA manifolds and tube assemblies. This distinction is important because the TDS-11SA contains numerous fluid-control components with different functions and part numbers.

Role of the Manifold in the TDS-11SA System

Modern top drives incorporate multiple hydraulic, lubrication, braking, pipe-handling, and control circuits. Because many of these systems require separate fluid connections, manifolds provide a practical way to organize and route those connections.

The MANIFOLD ASSY 114174 should therefore be considered as part of a larger fluid-control network rather than as an isolated component. Its condition can influence the reliability of the connected tubing and circuit.

The TDS-11SA spare parts list includes numerous related tube assemblies, including MANIFOLD/LOAD STEM, MANIFOLD/BRAKE, ACCUMULATOR/MANIFOLD, MANIFOLD/SHOT PIN, and other tube configurations. This illustrates the extensive network of fluid connections incorporated into the top drive.

Why Proper Manifold Maintenance Matters

Top drive equipment operates in a demanding drilling environment where vibration, pressure fluctuations, temperature changes, contamination, and continuous mechanical movement can place stress on fluid-control components.

A manifold or its connected fittings may eventually require inspection or replacement because of leakage, corrosion, mechanical damage, damaged threads, or deterioration of sealing surfaces.

During scheduled maintenance, technicians should inspect the manifold assembly and its surrounding connections for:

· Visible hydraulic or fluid leakage

· Cracks, deformation, or mechanical damage

· Corrosion or surface deterioration

· Damaged threaded or connection areas

· Loose fittings or connections

· Deteriorated seals and O-rings

· Abnormal pressure or flow behavior in connected circuits

Any suspected problem should be evaluated according to the applicable equipment maintenance procedure before returning the top drive to service.

Related TDS-11SA Manifold and Tube Components

The TDS-11SA uses a large number of manifold-related components. Evergrow's spare parts list includes TDS-9/11 Manifold Assembly (EExd) OEM 114175 / Evergrow 171263, as well as Manifold Assembly, Clamp Cylinder OEM 118511 / Evergrow 177767. It also lists various tube assemblies connecting manifolds with brakes, accumulators, load stems, filters, shot pins, and other systems.

Because several manifold components have similar descriptions, checking the exact OEM reference and Evergrow part number is essential when ordering replacement parts.

For customers searching specifically for 114174, the corresponding Evergrow replacement number is 171261.
